FENCE-POST M OLD.

Specification of Letters Patent.

Patented June 12, 1906.

Application filed April 4,1905. Serial No. 253,874.

To aZZ z'qhom it may c mera: a

Be it knownthat I, PETER L. ScHAAr, a citizen of the United States, residing at Botkins, in the county of Shelby and State of Ohio, have invented a new and useful Fence- PostMold, of which the following is a specification.

This invention relates to molds; and it is particularly designed for use in making fenceposts.

It is an important object of the invention to have the mold formed in sections which are capable of being conveniently assembled and also readily taken apart to free the cast from the mold without damage thereto.

Other objects are to provide for conveniently and effectually binding together the sections of the mold without individually connecting the same, to arrange the mold for subjection to pressure to produce a pressed post, to provide for the convenient andling of the mold for carrying the same to and from the press, and to permit of the ready separation of the mold-sections to free the cast after the pressing operation.

The invention consists in the combination and arrangement of parts, as will be hereinafter more fully described, shown in the accomp anying drawings, and particularly pointed out in the appended claims, it being understood that changes in the form, proportion, size, and minor details may be made within the scope of the claims without departing from the spirit or sacrificing any of the advantages of the invention. 7

In the accompanying drawings, Figure 1 is a perspective view illustrating the mold assembled and bound together in the manner of the present invention. Fig. 2 is a crosssectional view thereof. Fig. 3 is a longitudinal sectional view of the mold. Fig. 4 is a detail perspective view of one of the sections of the mold. Fig. 5 is a similar view of another section.

Like characters of reference indicate corresponding parts in each ofthe'several figures of the drawings.

As embodied in the present invention each mold includes duplicate upstanding side sections, one of such sections being shown in Fig. 5 of the drawings and designated 1. This side section consists of a board, preferably soft pine, which has been boiled in linseed-oil to preserve the same against the eifects of dampness, When set up, the side rests upon one of its longitudinal edges, and its two longitudinal edges are converged, so as to form a tapered side section. Adjacent the narrow end of the section and upon opposite sides thereof are corresponding upright open-ended grooves or seats 2, and similar grooves or seats 3 are formed adjacent the opposite or wide end of the section. Extending between the seats 2 and 3, both upon the inner and outer sides of the section, are flanges 4, which have their outer faces flush with the adjacent edge of the side section and their inner faces beveled or inclined toward the section. The ends ofthes e flan es terminate flush with the inner side walls 0 the seats or recesses 2 and 3, so as not to obstruct the latter.

In Fig. 4 of the drawings there has been shown a section 5, similar in shape to the section 1 and designed to constitute either the top or bottom of the mold, .according to the manner in whichit is set up. This section is tapered, as described for the section 1, and is provided adjacent its wide end with a transverse groove or seat 6, intersecting its opposite edges, and also havmg another transverse groove or seat 7 adjacent its opposite end, each of these grooves or seats intersectin the opposite ends of the section and both 0 the grooves being in the inner face of said section.

Upon the inner face of the section and at each longitudinal edge thereof there is a longitudinal flange 8 flush with the adjacent edge of the section and beveled or inclined upon its inner face, the ends of each flange terminating at the inner side walls of the seats or recesses 6 and 7. The sections 2 and 3 are separated by the same interval that separates the seats 6 and 7, wherefore when the sections are assembled, with the section 5 constituting the bottom of the mold and the section 1 a side thereof, as in Figs. 1, 2', and 3 of the drawings, the seat 7 will register with the'seat 2 and the seat 6 with the seat 3, thereby to receive the respective end pieces 9 and 10.

It will here be explained that the flanges 4 and 8 are not absolutely essential to the present invention, as they are employed merely to give an octagonal shape to the post, and may therefore be omitted without departing from the spirit of the present in.- vention.

If it is desired to have corrugations in the exterior of one side of the post, one of the sections, as shown in Fig. 4, may be provided upon its inner face with transverse ribs 17, and another upright side section, as shown in Fig. 5, may be provided upon its inner face adjacent its narrow end with a boss or projection 18, designed to form a socket or recess in one face of the post adjacent its upper end for the accommodation of a brace or prop.

In setting up the mold a pair of side sections are placed with their flanged edges upon a base 19, which approximates the length of each section. The end pieces 9 and 10 are then fitted in their respective seats and the entire mold then embraced by a clampingframe made up of longitudinal side bars or rails 20 which converge in conformity with the convergence of the mold and are connected by terminal cross-bars 21 and 22, which lie at the opposite ends of the mold, the extremities of the side bars or rails being formed into handles 23, projecting beyon the cross-bars. Upon each side rail 20 there is a depending hook 24, designed to engage beneath the base 19, while other hooks 25 and 26 depend from the cross-bars 21 and 22, respectively, so as to engage beneath the adj acent ends of the base. The cross-bar 22 is designed to en age the narrow ends of the upright sides 0' the mold, and the side bars or rails 20 are of a length to project slightly beyond the wide ends of the side section, the cross-bar 21 being provided in its under edge with upright seats or notches 27 in alinement with the respective side sections 1, so as to receive wedges 28, which are driven downwardly between the seats and the side sections 1, each wedge being connected to the cross-bar by a suitable flexible connection 29, preferably a chain, to prevent loss of the wedges when not required for use. When the mold has thus been set up, the side and sections are securely bound to ether by the frame and are also connected to the base through the medium of the frame and the hooks 24, 25, and 26. The materialto be molded is then introduced through the open top of the mold, and the section 5 is then placed between the tops of the side sections 1, so as to constitute a top for the mold, said top of course resting upon the material to be molded and projecting slightly above the top edges of the sections 1. The entire mold is then lifted by means of the handles 23 and carried to a press, so as to subject the top 5 to a suitable amount of pressure for producing a pressed post. When the pressing operation has been completed, the mold is removed from the press, the top 5 taken out, and the wedges 28 removed, whereupon the clamping-frame is taken from the mold, and the several mold-sections are then free to be removed from the cast.

While only one mold has been shown in Fig. 1, it will of course be understood that any number of molds may be successively set up, according to the width of the clampingframe, although in practice only a single mold will be clamped within the frame 20, as it would be diflicult to handle more than one mold at a time. However, by reason of the fact that the grooves 2 and 3 are upon the in ner and outer faces of the sides of the mold a series of molds may be conveniently set up with a single section common to adjacent molds.

If desired, a wooden strip 30 may be embedded in that surface of the cement which is exposed through the open top of the mold in each form thereof, as shown in Figs. 2 and 8, said wooden strip serving for the attachment of the fencing.

Having thus described the invention, What is claimed is 1. In amold, the combination with a moldbody, of a clamping and carryin frame capable of embracing the sides and ends of the mold and provided with carrying-handles, means carried by the frame for detachable engagement with the bottom of the mold to support the same upon the frame and wedges to be driven in between the body of the mold and the frame to clamp the former within the latter.

2. In amold, the combination with amoldbody, of a combined clamping andcarrying frame to embrace thebody and provided with dependin hangers for engagement with the bottom of the mold.

3. In a mold, the combination with a moldbody, of a combined carrying and clamping frame capable of embracing opposite sides and ends of the body, handles for the frame, and hangers depending from the frame for enga ement with the bottom of the mold.

4. In a mold, the combination with a moldbody, of a combined clamping and carrying frame comprising spaced longitudinal bars embracing opposite sides of the body, crossbars connecting the side bars and extending across the respective ends of the body, one set of bars havin their ends formed into handles, hangers (Iepending from the frame for engagement with the bottom of the mold, and one or more wedges to be driven in between the frame and the mold.

5. A combined, clamping and carrying frame for molds comprising spaced longitudinal bars, terminal cross-bars connecting the same, one set of bars having its ends formed into handles, and hangers depending from the frame for engagement with the bottom of a mold.

6. A combined clamping and carrying frame for molds comprising spaced longitudi nal bars, terminal cross-bars connecting the longitudinal bars, one set of bars having their ends formed into handles, hangers depending 5 from the frame for engagement with the bottom of a mold, and one or more wedges to be driven in between the frame and the mold.

In testimony that I claim the foregoing as my own I have hereto afiixed my signature in the presence of two witnesses.
